In this tense and unnerving horror thriller, Angela, a former nurse at a Planned Parenthood clinic, offers help to women from her home after the local government forced the clinic to shut down. Believing that Angela is coercing women to get abortions, the Baarker family - a group of dangerous and fanatical right-wing Christians - lead by preacher Jeremiah, seek vengeance. They claim that God has ordered them to cleanse the land, and the sin that Angela represents. Along with her police officer boyfriend, Angela decides to stand her ground against the church. Jeremiah is infuriated when Angela gives his wife (Jewel Staite) birth control. When he receives word that a young girl has had an abortion the Baarkers start to hunt the child down. Angela takes her in and vows to protect her. But as the tension between the two sides mounts, the Baakers' zeal turns murderous and the rule of law decays into a brutish mob mentality, leading to a horrifying turn of events.
